Lymphoid Organs & Lymphocytic Traffic

Frage	Antworten
Role of Lymphoid Organs	Origin or initiation of lymph cells
Central	Thymus & Bone Marrow
Bone Marrow	B cell production & maturation
Thymus	Maturation of T-Cells
Peripheral	Lymph Nodes, spleen, peyers patches
Peyers Patches	T/B cell activity & antigen trapping collections of cells
Lymph Node	Encapsulations of B cells connected by lymph vessels
MALT	Mucosa Associated Lymphatic Tissue i.e Peyers Patches, tonsils
Role of Lymphocytic Traffic	Immune surveillance that allows activation of lymphocytes at site of infection
Immune Surveillance	Constant recirculation of lymphocytes to maximise antigen/pathogen detection
Lymphocyte recirculation	Pass from blood --> Lymph System (if antigen is not present it moves back into the blood)
Encountering Specific Antigen	Lymphocyte proliferates clonally
Naive lymphocyte	L. that has not yet encountered antigen it's specific for (recirculate constantly)
Effector Cell	Activated (armed) lymphocyte by its antigen
